Forum Linux.gentoo probleme a installer kde

Salut, je vend d'installer gentoo 2007.0 sur ma machine. Elle marche assez bien sauf que je ne peut pas installer kde-3.5.5 ni kde-3.5.7. Comme vous pouvez le voir je met si dessous le message d'erreur qui me sort soit avec
emerge kde
emerge kde-meta
emerge kdebase-meta
et ainsi de suite

comment puis je installer kde sans tout recommence a zero, sur quelques site ils ont indiquer que de faire un emerge --sync arrange ce genre de problème mais ici ca na rien regler.

Ps: j'oublier j'avais deja kde d'installer dans mon ordi mais il y a eu un probleme et je fait une emerge --unmerge kde
